My 1998 3 liter MerCruiser has a tube from a rubber cap in the top of the
valve cover (no PVC) to the spark arrestor over the carburetor. It's held to
the spark arrestor by a tab on the metal strap that holds the spark arrestor
to the carburetor.

Hello.

When I bought my boat the oil breather tube came without a cover.

Do you know where I could find one for a 3.0 liter GM motor used in an
88 OMC cobra I/O? What should I expect to pay? If I can't find the
original part, is there some way to cover the breather without blocking
it?

Thanks.
